Creating a Video Wall Mosaic with DISPLAX Tile

When using multiple DISPLAX Tile units together, you can merge them into a single large display (mosaic) using your graphics card control panel.
This allows the operating system and applications to treat all Tiles as one unified screen.

Overview

A video wall mosaic combines multiple physical displays into a single logical display.
This configuration is handled entirely by the graphics card, not by DISPLAX Connect.

ℹ️ Note:
The example below uses an NVIDIA graphics card, but similar steps apply to other vendors that support videowall or mosaic features.

⚠️ Important Before You Start

Before configuring the mosaic:

  • Ensure all Tile units are set to Landscape orientation in:

    Windows Settings → Display

  • This must be done even if the final installation will be Portrait.

  • Orientation changes for portrait layouts are handled later inside the Mosaic setup.

Skipping this step may result in incorrect display mapping.

Step-by-Step: NVIDIA Mosaic Setup

Step 1 – Open NVIDIA Control Panel

  1. Right-click on the desktop

  2. Select NVIDIA Control Panel

Step 2 – Launch Mosaic Setup

  1. Navigate to:

    Workstation → Set up Mosaic

  2. Click Create new configuration

Set up Mosaic

Step 3 – Configure Mosaic Topology

In the NVIDIA Mosaic Setup dialog:

  1. Select:

    • Number of Tile displays

    • Mosaic topology (rows × columns)

    • Desired orientation

  2. Click Next

Configuration

Step 4 – Select Displays and Refresh Rate

  1. Select all Tile displays to be included

  2. Set the refresh rate to 60 Hz

  3. Confirm resolution and frame rate compatibility

⚠️ DISPLAX Tile installations are validated at 60 Hz for stability

Step 5 – Arrange Tile Positions

  1. Arrange the Tile displays to match their physical layout

  2. Ensure alignment matches the real-world installation

  3. Click Next, then Apply

Apply

Step 6 – Confirm Changes

  1. When prompted, click Yes to keep the changes

The Tiles are now merged into one large display

Bezel Correction

After creating the mosaic:

  1. Proceed to Bezel Correction

  2. Typical bezel correction value is 24 pixels

    • This may vary slightly depending on the installation

  3. Click Apply, then Finish

Bezel correction ensures visual continuity across Tile borders.

Final Notes & Best Practices

  • Always perform mosaic setup before touch calibration

  • After mosaic creation:

    • Recalibrate touch using DISPLAX Connect

  • Test:

    • Full-screen applications

    • Touch accuracy across Tile borders

  • Ensure GPU drivers are up to date

⚠️ Common Mistakes to Avoid 

  • Setting portrait mode before mosaic creation

  • Mixing different refresh rates across Tiles

  • Skipping bezel correction

  • Calibrating touch before the mosaic is created
